As always, stick with Leaky for the latest.As a reminder, the team at Pottermore have asked us to help collect your questions so they can answer some things for you. Not everything (for instance, about exactly what will happen on July 31, or more details about J.K. Rowling’s involvement) can be answered, but if you want some more detail about the site, how to compete for the house cup, how to progress through the story, etc., then this is the opportunity.Just TWEET your question to @leaky using the hashtag #pottermore starting right now. Leaky’s team will sort through them and send the most-asked questions to Pottermore by the end of this week.
